6.5" component set

Tim · Post by **Tim** » Wed May 05, 2010 5:24 pm

I am going to get a new component set up for my truck. Most likely MB Quart family, aint really decided which ones yet.

I know this is a very general question and could lead to alot of answers, but If I cross my subs over at say 75-80 hz. Where would be a good place to cross my 6.5 at. Im going to run a seperate amp for the comps. So what would be a good range for the woofers in the component set??

cross your subs at 50Hz with an 18dB slope, and set the HPF for the comps at 100Hz, 12dB slope.
the roll-off between the HPF and LPF will cover the 1 octave gap between the cutoff points. 80Hz is too high for subs. They'll sound really boomy, and you'll start getting vocals and such from them. They'll lose their "tightness" and definition. Your 6.5" will do fine rolling down to the subs.

I typically cross around 60hz with 12db slope but that suits my car my mids and my taste in music. I don't think there is any specific setting adjust it till it sounds good to you.

I was just giving him a starting point to work from.
I prefer a steeper slope for a sub just to keep it tight. You'll notice most fixed slopes on sub amps and head units with a LPF are at 24dB, while the HPF are usually 12dB.

which setting will I want my crossover set on, on my mid amp?? HP LP ALL

Im sorry for such newb questions, I just never ran a two amp setup before. Always before I was about bass, and now that since im older "boom" is just not as important as it used to be.

Thanks for all the help,

HP (high pass) for the "full range" amplifier driving your door speakers. You'll want it set to 100 or 120Hz.

The subwoofer amplifier will be set to "LP" and 50 or 60Hz.

since this is a 6.5 component thread. Ill just use the same one to post my decisions on which set to get.

Here they are:

As you can see the Bostons are quite a bit more expensive. Now I know price does NOT dictate quality either way. So Im in no way using that as a factor.

You guys give me your opinions on which way I should go.

Thanks for the help in deciding.

Another quick way to think of it is to think HP = High Pass That means it allows any frequency's higher than what its set to to "Pass"

Low pass would be freq lower than the setting to pass.
